How to remove from one list all the items in another?

Question

I\'m reading a set of rows from a remote database, and a similar set from a local database, and then using RemoveAll to get rid of remote rows that are already present locally..

Answer 1

One way is this:

    remote_events.RemoveAll(Function(e) local_events.Exists(Function(f) f.Identifier = e.Identifier))
